DENTAL Fltibll'll HOLDER.

Application 'filed April 26, 1922. Serial No. 556,687.

To all whom t may concern Be it known that l, ARTHUR F. SHAW, a citizen of the United States, and residentof Columbia, in the county ot Richland and it State of South Carolina, have invented certain new and useful Improvements in Den-` tal Film Holders, of which the following is a specification.

in taking skiagraphs of the teeth it has 10 been found more or less `difficult to hold the film in proper position so that it can be held against any tooth or portion ot the jaw of which a photograph is desired. ll/lany expediente have been` tried but as yet none lit have come into general use.

An object of my invention is to provide a cheap and simple device for holding the films in any desired position that notwithstanding its simplicity will be very eitective.

Another object is to provide such a holder that can be used with any form of the lli-ray films in general use and the parts of which `can be quickly assembled.

Another object is to provide such a holder that canl in whole orpart be provided with each film and thrown away after one use, thereby avoiding the necessity of sterilizing any parts and at the saine time increasing the cost only in a veryl slight degree.

Other objects will be apparent 'from the following detailed description of the invention and the appended claims.

in the drawings:

Figure 1 is a 'front view of one common form of -X-ray lm pack.

Figure 2 is a rear view of the same showingl part of my device applied thereto.

igure 3 is a section on the line 3-3 of Figure 2.

Figure a is a view of the entire device assembled.

Figure 5 is a rear view showing a modiiication in one element of the device y Figure 6 is a perspective View of a modification with the parts in one position.

Figure 7 is a similar view ot the same modification with the parts of the invention partially assembled.

Figure 8 is a view of the same modification in assembled position.

Figure 9 is a perspective view oi a slight modification of the form shown in Figures 6, 7 and 8.

Figure 10 is :il/section through Figure 8.

One common form of X-ray film pack is mit shown in Figure l and designated A. As shown in section in Figure 8, this pack is composed of one or more thicknesses of paper l5, the sensitized plate C and a metal backing D which has its edges turned over at D (Figure l) to hold the parts together.

lt employ a button l of the same general form as a collar button but preferably formed of soft rubber. The base ot this button is placed against the back of the film pack. i paper or adhesive cloth inember Q having a hole therethrough for the button l is caused to adhere to the back of the film pack A as clearly shown in Figure 3, and holds the button l in position. A short piece of wood 3 or similar material is provided with an opening 3 of the proper size to receive the free end of the button. lt is intended that the button shall fit snugly in the opening 3 so that the part 3 will serv@ as a handle. Obviously it will be easy to handle the film pack and place it in any desired position in the mouth beside the selected tooth.

Figure 5 shows how the paper or cloth back 2 may have a slit t cut therein to facilitate assembly of the button and back portion. ln other respects the device is identical with that already described.

Figures 6 to l() inclusive show a modification in which a small envelope 5 is em ployed which is the proper size to hold the film pack. A button l corresponding generally to the button l, although illustrated for variety of slightly different shape, has its small end passed through a hole 7 in the `flap 6 as shown in Figure 6. The iiap is then turned down and sealed as shown in Figure 7, and the strip or handle 3 can be applied in the usual manner.

A. slight variation ,in this form is shown in Figure 9 wherein the broad base of the button il is placed within the envelope and passes through both flap portions thereof. When the handle 3 is applied it holds all parts in assembled position thus avoiding the necessity of sealing down the flap of the envelope.

The handle 3 may be made of wood and thrown away after one use, or it may be made of some other material that can be cleaned and sterilized. While the button l is preferably made of sott rubber, it is obvious that other materials may be used witbout departing from the spirit of the inven tion. The button element may' be one mein. ber of a snap fastener and the handle 3 may be provided with the corresponding element instead of merely having an opening therein. The backing or retaining element 2 or 2 may be made of paper or equivalent substance, although I find adhesive tape or cloth very convenient and eieient. It is obvious that the size, proportions and materials may be varied Without departing 'from the invention, Which in general is to be regarded as limited only by the scope of the appended claims.

I claim as my invention:

l. A dental film holder comprising a handle. a button member detachably connected thereto, and means for supporting a film pack by said button.

`2. A dental film holder comprising a handle, a rubber button member detachably connected thereto, and means operatively connecting a film pack to said button.

3. A dental lilni holder comprising a rubber button member having a shank and a having its shank passed through the Hap of the envelope, and a handle detachably engaging said shank.

5. A dental film holder` comprising an envelope for containing a film pack, a button having its shank passed through one side of the envelope and the flap, and a handle detachably engaging said shank.

In testimony whereof, I have hereunto subscribed my name.

ARTHUR E. SHAW.
